To all 1071 om it may concern:

Be it known that I, LEWIS Kiitiixo, oi' the. city of Biiltiinc and State of Maryland, have invented certain Improvements in Bottle-Sealing" aps, of which the following is a specification. I

This invention relates to certain. lDi roveiiienis in :1 bottle sealing ca) which enilio'dies as essential features tl-iereoi', a crown having a. pendent flange the lower edge of which is adopted to be turned in and under shoulder generally produced in bottles by the projection of the head beyond the neck, to hold. the crown in Contact with the lip of the liottle, and a jOilit-fOIIiilllg ringer disk which is iiiclosed by the pendent flange and in contact with the crown.

The said invention consists iii 9. peculiar formation of the flange the sealing-r cap, as will hereinafter fully appear.

in the further description o the sziid in vention which follows, reference-is made to the accompanying drawing iorniing it part hereof, and in whit-h v Figure 1 is a central vertical section of o bottle head provided with the improved sealing cap, the cap being shown it would appear before the sealing operation. Fig. shows the bottle head and sealing cap idler the sealing operation. Fig. 3 is s partly broken edge. view oi the sealing cap alone the same being enlarged to more fully ill istrete the nature of the corrugations at its edge. Fig. 4 illustrates the sealing cap provided with s. joint-forming disk instead of e ring shown iirFigs. l and 2.

Referring now to Figs. 1, 2 end 3 (ii-the drawing, 1 represents a bottle heed having theshoulder-i (1/. The bottle cap which is priferably' formed of tin plate, consists of the crown 2, the pendent annular flange 3 and the compressible joint-forining ring 4.

To fully understand the nature of the present invention it must he bore in mind that in drawing or stamping a bottloseal or any cap-slniped device from it flat disk, the portion of the iiiiiterial which may be termed the flange, owing to its reduction i'i'olii the original diameter iiiiist'necessarily he lengthened or tillljlflllifli or criinped,v and p in any case the i'naterial is stiliened. .(hgitll'l, if the extreme edge of the flange turned Patented March 24-, 1903.

: causes a further concentration of the material iwaid, the renewed reduction in diameter and an additional incrense'iii rigidity.

As in the present invention hereinafter fully described, the edge oi" the flange is turned in and consequently reduced in diameter, end has to be further reduced in diameter in the application of the cap to s bottle head, the Ol) }l3 3t of the said invention is to facilitate the last nnined reduction in diameter, or make it possible to reduce the diameter of the inturnededgeoi the Henge without i'n-iterially disturbing the molecular condition of the metal. i

My invention therefore consists iii. corrugeting or crimping the inturned edge of the flange, which corrugation b, as the said edge is reduced in diameter in the zip lication of the sealing cap to the bottle iead, s

merely accentuated, the eriinps being deepcried and slightly closed. By this construction of the flange of the sealing cap, less pressure is required to apply the cop to the bottle head, and less force necessary to re.- move; the cap from the bottle; While reflection oi the compressed portioirof the cap upon the withdrawal of the capping tool if not entirely obviated, is materially re duced.

in l s compressible dish 4 is shown as substituted for the joiiit-iorn'iin ring l.

The cupping operation consists in changing the sealing clip from the form showi in Fig. l to that illustrated in Fig. 2 in which the corrugated edge of the clip is brought tightly in contact with the bottle at a point slightly below the shoulder a of the bottle head.

I claim as inv invention:

1. 'ln combinhtion with a bottle head, it sealing cop for the same which compr ses a crown, a pendent annular tliiiiee and a oiiitforining device, the edge of the said flange bcin turned inward and corrugated, sub-.

stentiallyss specified. o I

2. A sealing cup for It bottle which coneis of crown having ft downwardly extend hie; annular flange the edge ol which is turned inn'zird rind corrugated, substentiellu us speci'i'ied.
